    How to read inductor specs?

    I have a broken samsung galaxy s10 with missing inductor. I want to replace the missing inductor and I have found some vendors. But I don't understand how to read the specifications of the inductor. The specs are:

    INDUCTOR-SMD;470NH,20%,2520,T0.8,0.029OH

    I understand that the inductor is 470 nH with 20% margin, and the size is 2520 or 1008 (imperial measure), but what do T0.8,0.0290OH mean? I can't find any explanation on the web.

      0.029 ohms DC resistance?

          I also notice that the resistance is sometimes mentioned for inductor... as well as current.

              Corsair CX750M [Model 75-002019] - burned output toroid inductor
              by momaka
              Looks like I may need a little help from the PSU experts (or anyone really! ) I have a Corsair CX750M (Model 75-002019) that I picked up for free about 4 years ago. This is the PSU:



              So here’s what’s strange about this one: it appears to work normally (normal output voltages) and any PC is stable with it. However, after a while (typically 10-20 minutes, but time can vary depending on the load), there is a sweetish smell of burned magnet wire insulation emanating from the PSU. Upon opening the PSU after this happened (many times), I was able to confirm...

              MacBook Air A2337 (820-02016) - 5V, won't turn on - please help me understand why
              by mkdj
              Hello everyone,

              About me, my goal and the equipment I (don't) have:
              I am brand new to this forum, and I am eager to learn about repairing laptops. I have an engineer background although I haven't done electronics for a while. I have watched several Youtube videos in the last two months, trying to understand how to diagnose a faulty motherboard. I have a USB-C Amp meter and a classic multi meter. No DC Power Supply to inject voltage, no soldering iron to replace components.

              About my issue and my goal:
              A friend of mine has a MacBook Air M1 A2337 that does not...

              Lenovo S145 -15iwl vcore inductor warm.. looking with oscilloscope there is a spike.
              by Bartoloni
              Hi, i have a Lenovo S145 that after 20 seconds shutdown and restart (it's working correctly on thse 20 seconds)
              everything seems ok, but on Vcore inductor ( this is an i3 with just 1 switching power supply for CPU)

              there is an output to teh CPU with a spike.. seems that inductor can't handle the input...
              replaced the capacitor (330) and the inductor (R15) without any change
              any idea? very thank you!

              input of the inductor seems as usual... only strange thing is that the upper/lower voltages seems to be 21V (main power line is 19.3) ... but not sure this...

              Blown Inductor on WD My Passport
              by silver60618
              Hi Guys, my WD My Passport drive powers on, then powers off. Ive taken out the motherboard and identified a blown Inductor. Im trying to recover my data only

              Reading between leads show nothing. If I removed this Inductor, what would be a suitable replacement? am I correct that its a ferrite Inductor is to just filter noise?
              Ive seen people just bridge them, any harm in replacing it with a differnt value Inductor?

              Lastly am I correct in thinking there is no polarity on the smd component?

              Thanks!...

              Operating frequency for motherboard common mode inductor/filter
              by J_T
              I have a question - I have replaced the PSU on my own iMac Pro. However, when removing the motherboard I knocked of a 120 OHM 30% 0.3A small surface mount common mode inductor/filter (~0602 size) in the ethernet circuit near the female RJ45 port.

              The closest match I can find on Mouser is 120 OHM common mode inductor at 100MHz - my question is this frequency correct for a motherboard? The schematic for the motherboard only provides '120 OHM 30% 0.3A' and the TDK part number does not return anything in google.

              Sorry, I am not experienced hence a basic question.
